Definition from buildingSMART: Inclined slab segment, normally providing a human circulation link between two landings, floors or slabs at different elevations.

An IfcRampFlight is normally aggregated by a ramp (IfcRamp) through the IfcRelAggregates relationship, the ramp flight is then included in the set of IfcRelAggregates.RelatedObjects.

A ramp flight normally connects the floor slab of zero to two different storeys (or partial storeys) within a building. The connection relationship between the IfcRampFlight and the IfcSlab is expressed using the IfcRelConnectsElements relationship.

HISTORY New Entity in IFC Release 2.0.

Property Set Use Definition:

The property sets relating to the IfcRampFlight are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcRampFlight are part of this IFC release:

Geometry Use Definitions:

The geometric representation of IfcRampFlight is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are:

Local placement

The local placement for IfcRampFlight is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

Standard Geometric Representation

The standard geometric representation of IfcRampFlight is defined using the swept area geometry. The following constraints apply to the standard representation:
